NAVIGATION SYSTEMPFP:25915
System DescriptionAKS007IQ
The navigation system periodically calculates the vehicle's current
position according to the following three signals: Travel distance of
the vehicle as determined by the vehicle speed sensor, turning angle
of the vehicle as determined by the gyroscope (angular velocity sen-
sor), and the direction of vehicle travel as determined by the GPS
antenna (GPS information).
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and
indicated on the screen with a current-location mark.
By comparing the vehicle position detection results found by the
GPS and by map-matching, more accurate vehicle position data can
be used.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
TRAVEL DISTANCE
Travel distance calculations are based on the vehicle speed sensor input signal. Therefore, the calculation
may become incorrect as the tires wear down. To prevent this, an automatic distance fine adjustment function
has been adopted.
TRAVEL DIRECTION
Change in the travel direction of the vehicle is calculated by a gyroscope (angular velocity sensor) and a GPS
antenna (GPS information). As the gyroscope and GPS antenna have both merit and demerit, input signals
from them are prioritized in each situation. However, this order of priority may change in accordance with more
detailed travel conditions so that the travel direction is detected more accurately.
MAP-MATCHING
Map-matching is a function that repositions the vehicle on the road
map when a new location is judged to be the most accurate. This is
done by comparing the current vehicle position, calculated by the
method described in the position detection principle, with the road
map data around the vehicle, read from the map DVD-ROM stored in
the DVD-ROM drive.
Therefore, the vehicle position may not be corrected after the vehicle
is driven over a certain distance or time in which GPS information is
hard to receive. In this case, the current location mark on the display
must be corrected manually.
CAUTION:
The road map data is based on data stored in the map DVD-
ROM.

Can detect the vehicle's turning angle
quite accurately.
Direction errors may accumulate when the vehicle is
driven for long distances without stopping.

COMPONENT DESCRIPTION
NAVI Control Unit

The gyro (angular speed sensor) and the DVD-ROM drive are
built-in units that control the navigation functions.

Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining this data with the data contained in the DVD-ROM map.
Locational information is shown on LCD panel.
DVD-ROM Drive
Maps, traffic control regulations, and other pertinent information can
be easily read from the DVD-ROM disc.
Map DVD-ROM

The map DVD-ROM has maps, traffic control regulations, and other pertinent information.

To improve DVD-ROM map matching and route determination functions, the DVD-ROM uses an exclusive
Nissan format. Therefore, the use of a DVD-ROM provided by other manufacturers cannot be used.
Gyro (Angular Speed Sensor)

The oscillator gyro sensor is used to detect changes in vehicle steering angle.

The gyro is built into the navigation (NAVI) control unit.
BIRDVIEW™
The BIRDVIEW™ provides a detailed and easily seen display of road conditions covering the vehicle's imme-
diate to distant area.

BIRDVIEW™
Description

Display area: Trapezoidal representation showing approximate
distances (Wn, D, and Wd).

Ten horizontal grid lines indicate display width while six vertical
grid lines indicate display depth and direction.

Pushing the “ZOOM IN” button during operation displays the
scale change and the view point height on the left side of the
screen.
The height of the view point increases or decreases when
“ZOOM” or “WIDE” is selected with the joystick.
MAP DISPLAY
Function of each icon is as follows:
1. Azimuth indication
2. Position marker

The tip of the arrow shows the current location. The shaft of
the arrow indicates the direction in which the vehicle is travel-
ing.
3. GPS reception signal (indicates current reception conditions.)
4. Distance display (shows the distance in a reduced scale.)
